primary chain case noise
We took the Ajay for its maiden voyage with French plates on. There is an intermittent noise from the primary case, I have tightened the chain to see if that improves things, I wonder if there are any other suggestions as to what might be rubbing or scraping? Possibly the alternator rotor boinking the stator?

Re: primary chain case noise
Has it ? You *should* have also re-adjusted the drive chain (which will have loosened if you have tightened the primary chain).Slash wrote:I have tightened the chain to see if that improves things,
Presumably the noise changes with engine speed?Possibly the alternator rotor boinking the stator?
Does the noise occur when you are stationary (with th'engine running!) or only when going along? It's possible that it's a loose drive chain slapping or rubbing on the chainguard or primary case at the gearbox end and can sound as though it's from inside the primary case. Some drive chains are slightly wider than the originals and leave very little clearance at the primary case/gearbox drive sprocket end.
Be aware that if it is the rotor rubbing on the stator (there's only a couple of thou clearance) I've known them heat up allowing heated toffee-like insulation to weep out and eventually lock th'engine.

Re: primary chain case noise
If it is the rotor touching the stator, this will show up when stripped down, if that is the case get someone to take 5 thou off the rotor problem solved
